ERASEB FOB INK.

Specification of Letters Patent.

Patented'Oct. e, 1908.

Application filed October 8, 1907 Serial No. 396,398.

Be it known that I, JOSEPH-.CQWLEY HUss, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in' Erasers for Ink, of which the ollowing is a specification. v x j My invention has reference to eraser-s for I ink marks, and consists of certain im rovenents,.wh.1ch are fully set forth'in the ollow- 111g specification, and shown in the accompanyingdravvings, which form a part thereof.

I construction of eraser, which may be detach- .ably adapted to a pen holder, very much in the same manner as a penand be easily ma-- mfilted by'use of the holder.

The object of In'yinvention is to provide a object is, further to provide an exceedingly cheap and effective eraser which may be thrown away when dull and replaced I with a curved'shank adapted for attachment erasers remove v and 5-5 of A is the eraser proper, and B is the holder pen holder.

by a new one at a trifling cost.

My invention consists of an eraser made of steel having an erasing end and provided to a pen holder; further, in forming the erasmg end with one or more sharp edges referab yterminating in a point; and urt er, in

combining an eraser as bove set forth with.

a socketed holder in a detachable manner whereby the eraser may be removed and replaced when worn.

My invention also comprehends details of construction which, together with the features above s ecified, will be better understood by re erence to the drawings, in-

which i a Figure 1 is a perspective view of one of the from the holder; Fig. 2 is a plan view of the holder and eraser and Figs. 3, 4 and 5 are cross sections of my eraser respectively talli ren on dotted lines 3-3, 4-4,

which may be made the same as an ordinary I The eraser A is made of-steel and provided with the'curved shank C to fit into the ordinary curved groove or socket, in the holder B, and has an end D which is flattened and provided with the knife edges E E terminating in a point F. The edges E E are very sharp and highly tempered. The neck stamped u or ribbed in thecenter to give strength. hile I have two knife edges E,

it is evident that one would suffice. Also, whilel have shown the erasing edge termishaped in the preferred form.

The general shape of the erasing.

T iis eraser is nating in a point, the shape may be modified as found desirable and suitable for any spe- 'cial work for which the eraser 'is to be used.

end is V used with an ordinary pen holder in place of a pen and 'beingmade at atriflin be thrown away when it becomes ull and replaced by a new eraser oint'. These erasers may be made as cheap y as pens and being formed of sheet steel may be highly tem pered-to retain their sharpness.

My invention com rehends an eraser made in the form of detac able points ada ted for use with a pen holder or any han 1e, and hence I do not. limit myself to the minor details of construction as these may be modified without departing from the spirit of my invention.

Having now described my invention, what cost may I claim as new, and desire to secure by Letters Patent, is

having an erasing end formed of a fiat part having straight beveled edge'sto form knife edges uniting in a point' and having a neck portion cutaway operative to their extreme ends, and a shank integral with the erasing end adapted for atp tachment to an ordinary pen ho der and by which the eraser may be manipulated.

2. As an article of manufacture, an eraser having an erasing end formed of a fiat body having two opposite straight erasing knife edges terminating in a V point, said body being made flat and smooth on one side and having other side to form sharpknife edges, a shank curved in cross section for attachment to.a holder and by which the eraser may be manipulated and a neck ortion for uniting the shank and erasing end 3. A removable erasing point for a pen holder consisting of a flat pointed knife-edged art, a shank curved in cross section to fit the older, and a connecting neck stamped up in to render the cutting edges the edges ground off obliquely on the 1. As an article of manufacture, an eraser ribbed-like form connecting the shank and p knife-edged part.

In testimony of which invention, I have hereunto set my hand.
